In the following excerpt from his book-length study of Shiga, Mathy provides an overview of "Han's Crime." ["Han's Crime"] begins with a succinct account of the crime:

It was a very strange incident. A young Chinese juggler by the name of Han in the course of a performance severed his wife's carotid artery with one of his knives. The young woman died on the spot and Han was immediately arrested.

The body of the story consists of the examining judge's interrogation of the director of the theater, of Han's assistant in his juggling act, and finally of Han himself. The question is to decide whether the killing was deliberate murder or merely manslaughter.

The director testifies that Han's act is very difficult and requires steady nerves, complete concentration, and even a certain kind of intuitive sense. He cannot say whether the killing was intended or not.
